Improved device for operating blinds



Ntra STATES Arena" OBEN WILLIAMS, OF GOUVERNEUR, NEW YORK.

Specification forming part of Letters Patent No. LllQQS, dated pri 1564.

To all whom it may concern.'

Be it known that I, OBEN WILLIAMS, of Gouverneur, in the county of St.Lawrence and State of New York, have invented a new and useful devicefor opening and closing window-blinds, and also for opening and closingthe slats thereof; and Ido hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure l is an inner side or face view of a window-blind having myinvention applied to it; Fig. 2, a vertical section of the same, takenin the line :v Fig. l; Fig. 3, a horizontal section of the same, takenin the line y y, Fig. 1 5 Fig. 4, an enlarged detached view ot' a pinionpertaining to the same, with the .parts to which it is connected, thelatter beingin section, as indicated by the line zz, Fig. 3.

Similar letters of reference indicate corresponding parts in thesevera-l figures.

This invention consists in having the lower hinge ofthe blind formed ofa semi-spherical socket provided with an internal gear, into which ascrew meshes or Works, the screw leing on a shaft which is fitted in atubular shaft, the latter passing horizontally through thejainb of thewindow-frame, and having a pinion upon it which gears into a segmentrackat one end of the lever, the latter being attached to the slatrod of theblind, and all arranged in such a manner that the blind may be openedand closed from the inner side of the window without raising the sash,and the blind-slats also opened and closed, as hereinafter fully shownand described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the frame of a window; and B a blind, which may beconstructed in the usual way, and attached to the frame A by hinges CO', the upper one, G, being constructed in any proper manner,but thelower one,C/,con strueted in a novel way, as follows: The part A ofthehinge which is attached to the blind is of hollow semispherical form,and has teeth e within it, which extends all around, and into which ascrew, b, gears a pin, c, on an arm, d, which is attached to the frameA, fitting centrally into the upper end of a, as shown ink jamb, e, ofthe frame A, and into a tubular shaft, E, which extends entirely throughthe janib e, and is provided with a crank, F, at

its inner end. The shaft D has a collar, f, upon it which bears againsta plate, g, on the outer side of the jamb, and it also has a collar, h,upon it at the inner side of said plate g. This plate g, which issecured to the jamb, and the two collars f h, prevent the shaft D fromhaving any longitudinal movement, as will be fully understood byreferring to Fig. 3. The orifice t' of the tubular shaft E at its innerend is square, and when the shaft E is shoved inward or toward the hingeC covers a square, j, onk the shaft D, so that when the shaft E isshoved inward and turned the shaft D will be turned with it, and thescrew b, in consequence of gearing into the teeth a of the semi-spherea., will open and close the blind B, and also secure lor hold the sameat any intermediate point between an open and a closed state. The innerend of the tubular shaft E is provided with a flange, k, having a toothor projection, Z, which, when the shatt E is pulled outward, catchesinto one of a series of holes, m, made in a pinion, G, which is fittedloosely on the shaft E, and is thereby made to turn with the latter.When the shaft E is thus pulled outward in order to connect the pinion Gwith it, the inner end of said shaftis off from the squarej on the shaftD,and consequently the screw b is not turned when the pinion G isturned, and when the shaft E is shoved inward, so that its orice 'i isover the square j, to turn the screw b, the projection l will be outfrom the hole m in the pinion. It will be seen therefore that the screwb and pinion Gcannotbe simultaneously turned by the shaft E.

H is a lever which is attached by a fulcrumpin, n, to the inner sideofthe blind B. One end of this lever is connected to the lower end ofthe Slat-rod I ot' the blind, as shown at o, and the opposite end isprovided with a segmentrack, p, into which the pinion G gears; hence itwill be seen that when the pinion G is turned the slats g of the blindwill be opened and closed, and that they may be retained at any pointbetween an open and closed state.

opposite end` with :L segment-rack, p, with which J:he pinion G gearsthe shaft'J D E, being` connected and disconnected7 and the pinion Gconnected with and disconnected from the shaft E, as shown, and allarranged to operate substantially as and for the purpose specified.
